I think as long as you really love the name, popularity shouldn't matter. It's a handsome, respectable name. So what if he's not the only Jacob in his class? Plus, if he's going by Jake most of the time, that sets him a bit apart.

Yeah, that doesn't bother me. My husband and I both have Top-10 names for our generation, and it has never been a problem or upset us. see "Jacob" and roll her eyes, like, "Oh look, ANOTHER one." I suppose, though, that it really doesn't matter. This is sort of the ultimate navel-gazing, isn't it?

As a teacher, I can assure you that the only names that teachers roll their eyes at are kre8tive spellngs, made-up names and absurd word names. Normal names like Jacob/Jake are always welcome.

Jacob is a great name, strong history, ages well, cute nn (Jake, which is why I assume your kids like it....my youngest named her new Build a Bear "Izzy" because of the show, lol) etc. Maybe you can compromise and put it as the middle name, and honor the wish of your other kids that way? Linus wanted to name Vio "Thomas" or "Diesel 10" when I was pregnant with her and strangely enough we put Liesel on the list except thought it "looked" to similar to his name..but that is another story...)

Top ten names when *not trendy* (meaning, popular for a short time then off into oblivion, like mine was....) are usually solid. It just matters if you care that its that popular.
Unless you are really smitten with it and feel that is his name, then go for it! Either way, a fun story, thanks Disney Jr!
